Definitions
- the invention concerns a device for fine machining workpieces, preferably for honing and/or fine boring cylinder bores in crankcases of internal combustion engines.
- honing methods for example, peak honing, friction honing, glide honing, free-form honing, position honing, brush honing, liquid honing, laser structuring etc. All methods differ with respect to the tools, the rotary speeds, the oscillation speeds and possibly the configuration of the tools and their feed action.
- honing machines For each honing method there are various honing machines. For example, for position honing a rotary speed of the honing tool of up to 2,000 min ⁇ 1 is required and simultaneously a stiff spindle support. For finish/plateau honing, on the other hand, a rotary speed of approximately 300 min ⁇ 1 and an articulated tool receptacle are required. When as a result of material changes or a workpiece change the honing method must be changed, the machine must be converted or another honing machine must be used.
- each working station is configured for performing at least one working step and at least part is designed as a honing station for performing a honing operation (DE 10 2004 053 503 A1).
- the invention has the object to provide an autarkic machining unit with which it is possible to perform as many different machining methods as possible, at least however different honing methods of the aforementioned kind and also fine boring (also referred to as fine turning) without requiring conversion.
- the unit should be utilizable in particular for cylinder bores in the crankcases for internal combustion engines.
- each machining unit comprises an electromotorically driven spindle, an electromotoric or hydraulic drive that serves for generating the oscillating stroke movement of the spindle as well as for moving the machining unit into a working position, a tool receptacle with a rigid axis relative to the axis of the spindle and a feed device for radial feeding of the machining tools, and in that between the longitudinal sides provided with the machining units a service chamber is provided, that has an entry at one of the end wall connecting the longitudinal sides, and the machining units arranged at a longitudinal side of the module having at least one tool magazine correlated therewith that is arranged at the rear end wall of the module and in that within the module on or in the vicinity of each longitudinal side a machining station is provided, to which workpieces, through the gates arranged at the
- the important methods for fine machining bores may be integrated into one module, either such that up to four machining steps can be performed sequentially on one workpiece or also such that two or more bores can be machined at the same time.
- machining time is saved in that on a first machining station a first machining step (for example, pre-honing or fine boring) is carried out by the first machining unit, while the second machining unit may already pick up the required tool from a tool magazine for a second machining step (for example, finish honing).
- the machining unit comprises the following components:
- This machining unit is suitable for performing all honing methods.
- four machining units furnished with different tools, in one molecule it is possible to carry out on the same workpiece sequentially or on two workpieces simultaneously, for example, pre-honing (or fine boring), finish boring (for example, also position honing), laser structuring of the surface, and then, optionally, beveling.
- a complete, autarkic, flexible, modular machining cell is proposed that, on the one hand, can completely machine even workpieces that require several working steps but that also can be integrated into another production line within a very short mounting and/or converting time.
- the external dimensions are selected such that without demounting of components a transport on a roadway (width: 2.2 m, height: 3.55 m), by sea (container) and air (planks) is possible.
- the complete module employs as a drive of the spindle for the oscillation and the movement into a working position advantageously directly driven electric linear motors. They are developed further in an advantageous way such that the linear motor is configured in a U-construction (double-sided linear motor). In this way, it is free of any transverse forces during operation.
- the tool receptacle is provided with rigid support such that the spindle support is positioned at the smallest possible spacing relative to the beginning of the bore.
- a short and rigidly clamped honing tool is used and the spindle support is connected to the stroke oscillation.
- the machining unit can be used also for so-called position honing (DE 103 48 419 B3).
- position honing DE 103 48 419 B3
- the variety of applications is ensured moreover by use of a feed mechanism that may be integrated into the machining unit for honing and fine boring; this is disclosed in the prior patent application DE 10 2007 038 123.0 dated Aug. 4, 2007.
